Question

Which equation describes how the parent function, y=x², is vertically stretched by a factor of 4?Oy=x³+4Oy=(x+4)³Oy-4x²Oy=x*

Answer 1

Vertical Stretch

Vertical stretch occurs when a base graph is multiplied by a certain factor that is greater than 1.

If y = x² is the parent function, then stretching it vertically by a factor of 4 converts it to:

y = 4x²
